Electrodialysis (ED) is used to transport salt ions from one solution through ionexchange membranes to another solution under the influence of an appliedelectric potential difference.MPure ELECTRODEIONIZATIONAll E-Separation started with Electrodialysis
Ion exchange of ions withresin beads Ions in the resin migratetowardtheelectrodes,through IX membranes andinto C-chambers Water splitting produces H and OH- ions resulting incontinuous regeneration Impurity ions trapped in Cchambers by membranes, H and OH- recombine to giveH2OMPure ELECTRODEIONIZATIONHow EDI works
